Last week, in an essay criticizing Adobe's Flash platform, Apple CEO Steve Jobs drew attention to, among other things, its lack of support for touch--something essential to the experience of an iPhone or iPad. "Flash was designed for PCs using mice, not for touch screens using fingers," Jobs wrote.
But Flash is not very the only Web application that wasn't designed to handle touch, & the advent of touch-based devices "is very asking the whole Web to alter its behavior from what is been built up over twenty years," says Raju Vegesna, evangelist for Zoho, a company based in Pleasanton, CA, that produces a suite of complex online Web applications.
Individual issues are often tiny, but they add up to something more significant, Vegesna says. For example, roll-over interactions are common on lots of sites, but these don't work on touch devices. Other common tricks, such as hovering over a link to see the connected URL in the status bar, must be adjusted before a user can perform the same function.
A serious issue for companies like Zoho that focus on complex Web application is that lots of sites are not equipped with the ability to trigger the "soft keyboards" used on touch devices. Vegesna explains that touch devices pop up a keyboard when they recognize a text field on a Web page, but it is different for the more complex editors used as part of Zoho's online word processors. These usually cannot trigger a soft keyboard to pop up, leaving users frustrated.
